This is the error shown in the eclipse console

By the way, my tool is called SocialToolForLAMS.

Hi Felipe,

Did you use the tool builder
(http://wiki.lamsfoundation.org/display/lams/Tool+Builder) or did you attempt to build the tool from scratch?

It is definitely a problem with your Spring application context file, but without seeing the full error log and the applicationContext.xml file itself, its hard to say what is missing.

The NoSuchBeanDefined exception usually means exactly as it says. The name you used may not me the same (a typo) or the bean itself did not initalise correctly.

Please attach the entire files and we will be able to help you more

Hi Luke

Firstly, thanks for helping me.

I did use the Tool Builder with the forum tool skeleton.

I attached the lams.log (zipped) and the
socialToolForLAMSApplicationContext.xml file.

Hope it helps.

Greetings.

Here's the socialToolForLAMSApplicationContext.xml file.

Hi,

Assuming you're using the latest code from CVS, I think the problem is to do with the assumptions we've made for the package names used for all tools.  For example, your tool looks like it uses the following structure:

org.uach.lams.tool.socialToolForLAMS.service.SocialToolForLAMSService

If you look in lams_common/src/java/org/lamsfoundation/lams/beanRefContext.xml, inside the bean context.central is a list of contexts; among them is:

classpath*:org/lamsfoundation/lams/tool/**/*pplicationContext.xml

So basically the problem is that the LAMS core is only including those tools which have their context files under a package that starts with org.lamsfoundation.lams.tool.*

Can you try replacing that classpath line above with this?

classpath*:**/lams/tool/**/*pplicationContext.xml

If that doesn't work, try adding this line below it:

<value>classpath*:org/uach/lams/tool/**/*pplicationContext.xml</value>

I did both things, but no success.

I got this error:

Well it's a different error! In this case I think that's progress.

This error is saying that one the forum tool's beans can't start because there is a naming clash with one of the socialToolForLAMS beans. In your applicationContext.xml you might want to try renaming the 'timestampDao' to something more unique, e.g. 'socialToolForLAMSTimestampDao'.
